Additional Tips / Considerations
If possible, run speaker wires after AC wiring is in place to avoid
•
induced hum caused by close parallel proximity of the two types of
wire.
Avoid running speaker wires close to house electrical wiring for any
•
distance. If you have to run them parallel, leave two feet between the
wiring. Speaker wires should cross AC lines at a 90° angle.
Route horizontal wire runs through holes drilled in studs at roughly
•
equal heights.
Secure speaker wires in place against a stud along vertical runs with
•
insulated staples only. Do not pierce the wire insulation. Allow a bit of
slack for expansion of building materials.
